The LPAR Activity Report tracks the utilization and
environmental configuration information for one or more user
selected logical partitions at a monthly, weekly, daily, or
hourly level. Figure 2-193 shows an example of a monthly
LPAR Activity Report and Figure 2-194 shows the hourly form
of the report. In the hourly form, data for one day is
displayed by hour using the DAYS timespan of the PR/SM LPAR
Configuration and Activity File (HARLPC).
REPORT OPTIONS
The LPAR Activity Report supports standard time, SYSID, LPAR,
and external data selection. These selections are controlled
by the options discussed in Section 2.6.6.
DATA ELEMENTS
The elements reported are divided into the following
categories:
o Utilization Measures
o Environment
UTILIZATION MEASURES
Utilization is shown in terms of the percentage of the total
CEC consumed by the reported LPAR, and the percentages of
shared and logical processor utilization. Items reported
are:
CEC CPU The total available CPU time across the CEC,
TIME AVAIL: including both dedicated and shared processors
as derived by the following computation:
(PRSMTPP / INTERVALS) * DURATION
LOG PROC The total of the processor dispatch time for all
DISPATCH TM: the logical processors assigned to the LPAR.
When the Wait State Assist feature is disabled,
this is the time that the LPAR was actually
running on physical processors. When the Wait
State Assist feature is enabled, this includes
both the active time and the idle time the CP
spends waiting for PR/SM time slices to expire:
LPCTODTM.
PCT CEC The percent of the total CEC consumed by this
CONSUMED BY LPAR. It is computed as the ratio of the two
LPR: preceding report items times 100.
PCT LPAR The percent of the shared processor resources
SHARED UTIL: used by this PR/SM logical partition (LPAR).
This measurement does not apply to logical
partitions with dedicated processors, and will
have a value of zero: LPCPCSSU.
PCT LOGICAL The percent of time that the LPAR's logical
PROC UTIL: processors are in use for this LPAR. For LPARs
with Wait Assist disabled, this is the percent
CPU busy for the LPAR. For LPARs with Wait
Assist enabled, this represents the percent of
time that the processors are allocated to the
LPAR. (When Wait Assist is enabled, LPCTODTM,
the total processor dispatch time on which
LPCPCVPU is based, includes time when the LPAR
has put the processor in the wait state because
there is no work for the processor to do.):
LPCPCVPU.
PCT PROC The percentage of total dispatch time that was
EFFECTIVE effectively used by LPARs, exclusive of LPAR
DISP: management time. It is derived by the following
computation:
PRSMTEDT / PRSMTTDT * 100
PCT PR/SM The percentage of total dispatch time that was
OVERHEAD: attributable to LPAR management functions for
all LPARs in the CEC. This includes time used
in support of individual partitions, as well
as unattributable processor time. It is
derived by the following computation:
PRSMTLMT / PRSMTTDT * 100
LPAR ZAAP The percentage of time that the System z9
PROC Application Assist Processors (zAAPs) are in use
UTILIZATION: for this logical partition; derived from CA MICS
data element LPCPCVZU (LPAR zAAP Processors
Utilization). This data element is valid only
for System z9 and later servers.
LPAR TOTAL The percentage of time that the System z9
ZAAP PROC Application Assist Processors (zAAPs) were
UTILIZATION: dispatched to the PR/SM logical partition;
derived from CA MICS data element LPCPCTZU
(LPAR Total zAAP Processors Utilization). For
shared LPARs with Wait Assist enabled or for
dedicated LPARs, LPCPCTZU includes both busy
time and wait time. For shared LPARs with Wait
Assist disabled, this element is equal to the
percentage of shared zAAP resources used by
this LPAR. This element is valid only for
System z9 and later servers.
LPAR ZIIP The percentage of time that the System z9
PROC Integrated Information Processors (zIIPs) are
UTILIZATION: in use for this logical partition; derived from
CA MICS data element LPCPCVSU (LPAR zIIP
Processors Utilization). This data element is
valid only for System z9 and later servers.
LPAR TOTAL The percentage of time that the System z9
ZIIP PROC Integrated Information Processors (zIIPs) were
UTILIZATION: dispatched to the PR/SM logical partition;
derived from CA MICS data element LPCPCTDU
(LPAR Total zIIP Processors Utilization). For
shared LPARs with Wait Assist enabled or for
dedicated LPARs, LPCPCTDU includes both busy
time and wait time. For shared LPARs with Wait
Assist disabled, this element is equal to the
percentage of shared zIIP resources used by
this LPAR. This element is valid only for
System z9 and later servers.
ENVIRONMENT
The environmental measures appearing in this report reflect
the LPAR configuration and monitoring activity.
AV # OF LOG The average number of logical processors
PROCESSORS: assigned to this LPAR as derived by the
following computation:
LPCNOCPU / LPCTOACT
AV # OF ZAAP The average number of System z9 Application
PROCESSORS: Assist Processors (zAAPs) actually assigned to
the partition; derived from CA MICS data element
element LPCAVZAP (Avg Number of Active zAAP
Processors). This data element is valid only for
System z9 and later servers.
AV # OF ZIIP The average number of System z9 Integrated
PROCESSORS: Information Processors (zIIPs) actually assigned
to the partition; derived from CA MICS data
element LPCAVSUP (Avg Number of Active zIIP
Processors). This data element is valid only for
System z9 and later servers.
AV # OF IFL The average number of integrated facilities for
PROCESSORS: Linux actually assigned to the partition;
derived from CA MICS data element LPCAVIFL (Avg
Number of Active IFL Processors)
AV # ICF The average number of either internal coupling
PROCESSORS: facilities (for System z9 and later) or special
purpose processors (for previous systems)
actually assigned to the partition; derived from
CA MICS data element LPCAVICF (Avg Number of
Active ICF Processors).
# OF INTVLS The count of RMF recording intervals when the
LPAR ACTIVE: reported LPAR was active: LPCTOACT.
INTVLS W/WSA The number of RMF recording intervals in which
ENABLED: the LPAR Wait State Assist feature was enabled:
LPCWSECT.
INTVLS W/WSA The number of RMF recording intervals in which
DISABLED: the LPAR Wait State Assist feature was disabled:
LPCWSDCT.
INTVLS W/DED The number of RMF recording intervals when the
PROCESSOR: reported LPAR had one or more dedicated
processors while the CEC was operating in PR/SM
mode. These are processors defined to be used
only by this LPAR: LPCDEDCT.
TOTAL RMF The total number of RMF recording intervals in
INTERVALS: the reported time frame. This includes both
intervals when the CEC was operating in PR/SM
mode, and intervals when it was not: INTERVLS.
